本次设计的RS232 to USB转换器,RS232端所采用的baud rate仅为9600。并没有对其它baud rate
到 USB 作转换-The design of the RS232 to USB converter, RS232 terminal baud rate used in 9600 only. There is no other baud rate to USB conversion
8051核的DES源代码
使用C语言写的基于51核的DES原码,变量定义使用汇编。占用了130字节RAM,比我所见到的包括汇编编写的都要快。
-8051 nuclear DES use source code written in C language based on the 51 nuclear DES original code, the use of variable definition compilation. Occupy the 130 byte RAM, than I have seen in the preparation of the compilation must fast.
通过汇编语言设计将输入一组十进制数,按从小到大到顺序输出-Through assembly language will be designed to enter a decimal number one group, according to the order from small to large output
To write assembly code to implement a circular First In First Out (FIFO) buffer in the data memory of PIC18F452 microcontroller, using the microcontroller’s direct addressing mode and indirect addressing mode. To expand on the FIFO assignment and implement the FIFO solution on the QWIKFLASH PIC target board and display the FIFOSTATUS as LED indicators. Recall:
Flags within a file register called FIFOSTATUS:
• Bit 0: FIFO_full
• Bit 1: FIFO_empty
• Bit 2: attempt_2_read when FIFO_empty
• Bit 3: attempt_2_write when FIFO_full
